California sues to block Trump's national emergency — here are the other 15 states that joined the lawsuit

California led 15 other states in a lawsuit to block President Donald Trump from building a border wall through the declaration of a national emergency.

California Attorney General Xavier Becerra made the announcement of the lawsuit on Monday, which coincides with Presidents Day.

"Today, on Presidents Day, we take President Trump to court to block his misuse of presidential power," Becerra said.

He accused the president of being "willing to manipulate the Office of the Presidency to engage in unconstitutional theater performed to convince his audience that he is committed to his 'beautiful' border wall.

"We're suing President Trump to stop him from unilaterally robbing taxpayer funds lawfully set aside by Congress for the people of our states," he concluded.

Here are the 15 other states that joined the lawsuit:

Colorado

Connecticut

Delaware

Hawaii

Illinois

Maine

Maryland

Michigan

Minnesota

Nevada

New Jersey

New Mexico

New York

Oregon

Virginia

The president made many statements admitting that he would use the emergency powers of the presidency in order to circumvent the disapproval of Congress. Democrats have been stalwartly against the border wall, and they control the U.S. House of Representatives.

The president appeared to anticipate a legal challenge to his use of the emergency authority in comments to the media.

"We will have a national emergency, and we will then be sued. And they will sue us in the 9th Circuit, even though it shouldn't be there," the president said.

"And we'll possibly get a bad ruling and then we'll get another bad ruling and then we'll end up the Supreme Court," he continued, "and then hopefully we'll get a fair shake and we'll win in the Supreme Court, just like the ban."

The Democratic-controlled House Judiciary Committee has already opened an investigation meant to determine whether the declaration of a national emergency was constitutional.
